Abstract
An optical communication module in which an incident or emergent end of an optical fiber can be easily and precisely aligned with a light-emitting element or a light-receiving element. The optical communication module includes a base block that has a first surface and a second surface located opposite to the first surface, a microelement such as a light emitting element or a light-receiving element that contacts the first surface. The second surface includes an optical-fiber guide hole, and the microelement contacting the first surface and an optical-fiber received in the optical-fiber guide hole are separated by an intervening portion of the base block.
Claims19
An optical communication module, comprising:
- a microelement;
- a base block that has a first surface and a second surface located opposite to the first surface, a first face of the microelement contacting the first surface;
- a metal wire that is provided from a second face of the microelement that is opposite to the first face onto the first surface of the base block;
- and
- a substrate that has at least one driver circuit for the microelement, the driver circuit electrically connected to the metal wire;
- the second surface including an optical-fiber guide hole into which an optical fiber is inserted;
- and
- a portion of the base block separating the microelement from the optical-fiber guide hole.
An optical communication module, comprising:
- a laser;
- a base block that has a first surface and a second surface located opposite to the first surface, a first face of the laser contacting the first surface, the base block being made of a transparent member having an optical-fiber guide hole, wherein a light emitted by the laser passes through a portion of the base block toward the optical-fiber guide hole;
- a bonding pad provided on the first surface of the base block;
- and
- a metal wire that is provided from a second face of the microelement that is opposite to the first face onto the bonding pad.
An optical communication module, comprising:
- a first microelement including at least one tile-like microelement;
- a second microelement including at least one tile-like microelement is disposed above the first microelement with an adhesive,
- the adhesive contacting the substrate, and
- the first microelement being covered by the adhesive;
- and
- a base block, wherein the first microelement being bonded to the base block,
- the base block being made of a transparent member having an optical-fiber guide hole that defines a concave portion, and
- a portion of the base block being positioned between the optical-fiber guide hole and the at least one tile-like microelement.
